Digital Combined pH/ORP Sensor

E+H/Endress+Hauser

• Approved for use in Ex Zones 0, 1 and 2 with ATEX, IECEx, CSA C/US, NEPSI, JPN and INMETRO certifications. • Memosens 2.0 supports an extended memory unit to store calibration and process parameters for improved trend recognition, providing an ideal foundation for future predictive maintenance and enhanced IIoT services. • Simultaneous measurement of pH, ORP and rH values (in rH mode) delivers comprehensive process information as a solid basis for stringent process control. • An additional platinum electrode continuously monitors reference impedance for reliable electrode quality assurance. • Filled with stable gel electrolyte; the reference electrode features an ion trap for robust performance and anti‑poisoning capability. • Measurement results are immune to pressure and temperature fluctuations: the open‑aperture diaphragm effectively prevents adhesion on the lead. • Non‑contact inductive signal transmission ensures high process safety. • Minimised production downtime, extended electrode service life and reduced operating costs.
